how do I input ln7/ln2/5600 correctly in my calculator to get 2900 as my answer?

The way you typed it, it would mean

(ln7/ln2) ÷ 5600 = .0005

if you mean: ln7 ÷ (ln2/5600)
= .000123

can't get 2900 !

(ln2)/(5 ln2+ln7) and get 0.128

I have the same issue, no clue

To input the expression "ln7/ln2/5600" correctly into your calculator and get the answer as 2900, you need to follow the correct order of operations. Here is the step-by-step process:
